Assessment of economically valuable traits of apple varieties and features of the main elements of the technology for their cultivation in an arid climate

Abstract The purpose of the research is to create winter-hardy, large-fruited, high-yielding, high-quality varieties apple trees different ripening periods and their growing technology (use a biological product) in South Urals. was carried out on basis Orenburg Experimental Station Horticulture Viticulture - branch Federal State Budgetary Scientific Institution “Federal Selection Technology Center for Nursery ” from 1999 2020. Research objects were summer – “Orenburgskoe”, “Orenburgskoe krasnoe”, “Solntsedar” (K); winter pozdnee”, “Zimnee”, “Yuzhnouralskoe” (K). counts observations according generally accepted methods. As result studies, data obtained showed that property short stature as genetic trait resistance transmitted offspring during hybridization. “Zimnee” greatest increase productivity embodiment experience “Evrikor Forte + 7” 2.5 l / ha by 25.4%, 24.3% 22.2% respectively. Thus, application “Eurikor-Forte increased both number fruits weight, also yield studied varieties.
